is there one that could be blown or something as simple as that? It worked fine all winter for the heater but when I turned it on the other day for the a/c I discovered that it just don't work anymore. (relay or fuse) where could they be?

 

The location of the fuse is in your owners manual.

 

Is it the original Fan blower motor for your truck? If so, it's probably time to replace it. I just replaced mine a couple weeks ago. It worked okay during the winter, though noticeably weak. Then when the warm weather came it wouldn't blow at all. When I got it out I could barely move the motor shaft with my hand. That thing was just worn, rusted, and crusted. Not bad, for a 23+ year old motor. Also, my fuse panel below the drivers side dash uses one fuse for both heat and a/c. Mine was labeled from the factory. Yours might be in the same spot as well.

 

its in the fuse panel under the dash on the drivers side its a 30 amp fuse.

 

thanks guys, I'll check it out in the am. I just havnt had time to mess with it. I'm really just wishin it was simple cause I just put the heater core in march, and now the blower is probably toast.
